The French R&D Tax Credit (CIR) Explained for Foreign Companies

Are you a foreign company conducting R&D in France?

If your group carries out research and development activities in France, you may be eligible for the French R&D Tax Credit (Crédit d’Impôt Recherche, or CIR). This tax incentive remains one of the most generous in Europe, offering up to 30% tax relief on qualifying R&D expenses. However, eligibility and documentation have become increasingly technical, especially after the 2025 Finance Law reforms.

A powerful but complex incentive

The French R&D Tax Credit is a major lever for innovation — but also one of the most closely scrutinized.
Recent reforms have made it essential to master the compliance framework and maintain robust documentation.

Key updates in 2025

  • Reduction of the flat-rate overhead coefficient from 43% to 40%.
  • End of the “Young Doctors” enhanced rate scheme.
  • Exclusion of some expenses (patent costs, non-scientific standardization, technology watch).
  • Stricter tax audit procedures, requiring full traceability of all eligible expenses.

In short: the CIR remains an opportunity — but only if your structure in France meets precise legal and accounting standards.

How foreign subsidiaries can qualify for the French CIR

1️ Set up a taxable entity in France

Only entities established and taxable in France (subsidiaries, branches, or permanent establishments) can claim the CIR.
👉 All R&D expenses must be booked and traceable through the French entity.

2️ Provide technical and financial documentation

The French Tax Authority requires a detailed scientific report, in French, following the OECD Frascati Manual methodology.
Foreign groups must adapt their internal R&D documentation — often written in English — to meet French compliance standards.

3️ Anticipate audits and ensure consistency

Incomplete or inconsistent documentation can lead to a reassessment.
The goal is not only to claim the tax credit, but to secure it over time.

Turning the CIR into a competitive advantage

When properly managed, the French R&D Tax Credit can:

  • Reduce your R&D costs by up to 30%,
  • Strengthen France’s role in your innovation strategy,
  • Improve subsidiary profitability through optimized tax planning,
  • Enhance collaboration between headquarters and local teams.

The CIR is more than a fiscal tool — it’s a strategic asset for global companies investing in innovation.
